Astronaut

Astronaut does best in a controlled indoor environment or a sheltered outdoor site; consistent temperatures and good airflow are essential.

Expect eight to ten weeks of flowering indoors; outdoor harvests should be timed before persistent autumn rain compromises bud quality.

Watch for spider mites, aphids and botrytis; regular inspection and prompt treatment with suitable biological controls or manual removal keep issues small.

Reduce nitrogen and increase phosphorus and potassium during mid to late flowering; flush lightly before harvest if using salts-heavy feeds.

Yes, Astronaut suits small tents when trained with topping and low-stress techniques to control height and develop multiple colas.

Full-spectrum LEDs with good red output for flowering offer efficient yields and low heat; position panels to maintain even canopy light across the tent.

Keep relative humidity around 40–50% in flowering to prevent mould, and use dehumidifiers or controlled ventilation during damp spells common in cool northern summers.

SCROG and SOG both work well; mainline or topping combined with selective defoliation produces denser buds and better light penetration.

Create a sealed grow room with extraction and fresh air intake, use full-spectrum LEDs, maintain stable temperature and humidity, add carbon filtration for odour and ensure good circulation with oscillating fans.

Harvest when trichomes are mostly cloudy with some ambers for balanced effects; check multiple bud sites to ensure even maturity.
